INTERLOCKING MECHANISM ron PARTY-QOLUM'N-VOTING MACHINEK Specification of Letters Patent.

Patented July 16, 1912.

Application filed September 25, 1899. Serial No. 731,509.

a citizen of the United San Francisco, cisco and State States, residing at in the county of San Franof California, have invented certain new and useful Improvements in;

Interlocking Mechanism Voting Machines, a specification. 7

An important class of voting machines has the names of candidates of the respective 1parties. arranged in vertical columns or the respective offices in rows. For

this class of machines it is necessary to provide or actuated by each of the keys of a plurality of rows. Thus, if there'are, say, ten such interrelated rows, and eight party columns,

for Party-Columnof which the following is it must be possible to vote any ten keys selected indiscriminately out of the eighty keys in the ten rows and eight columns a'nd that then the remaining seventy keys shall be automatically locked.

The object of my invention is to proyide a mechanism of this character which shall.

rmit of rapid adjustment of'the machine or different elections; that is, so that the arrangement of the rows .of keys for, the various oifices may be changed with facility and without the necessary of removal of any of the parts and substitution of others of difierent dimensions. Further to provide an interlocking mechanism which will admit of a machine being increased or reduced in size when desired by the inclusion or removal of one or more columns of keys to tickets, with slight. extra expe conform tomariations in the number of party use for disa sembling and re-assembling the machine.

A novel and important, feature of my invention is that by my construction I am enabled to use rows and columns of voting ena. corresponding nearly inform and size with keys with a space for the name of the candidate to be voted for at the side of each.

key, which space shall be of considerable length in proportion'to its height thereby ling a votlng machine to be constructed the ordinary form of ballot sheet in; use before the introduction of voting machines,

which sheet contains. the names of all candidatesf'of the same partyin sin le columns and. the names of all candidates or the same interlocking mechanism related to ofice in a row, the space devoted to each name being about high and from two to three inches long. This has been found the most'convenient form of ballot sheet as it contains the names three-eighths of an inch of the candidates in the most compact form and is the most convenient for the voter as he can more readily follow the names 10f candidates of the same party. a

It has not heretofore been practical so far as I am aware to provide a voting machine in which the names can be arranged to such ballot sheet, said spaces being close the divisions thereof resembling. in form and size those of the old style ballot sheet. By the use of my invention this can be done. My invention also resides in. the novel construction, combination, and arrangement of the parts, hereinafter fully specified, and particularly pointed out in the claims.

have

connection to the train of carriages, detached 'from the roller channel; Fig. 14 is a vertical section through the pivotal connection 30;

65 iii-spaces approximating in form and size.

The arrangement shown is that common to' machines of the class to which my invention relates, that is, the column on the left contains the list of offices to be filled or voted for, and the succeeding columns contain the names of nominated candidates for said oi'fices arranged vertically in columns according to party. In addition to this a column on the right is devoted to the irregular or scattered vote.

In the columns for the names, on the rightof each name, is a key 4, on the end of a push rod 5, (see Fig. 4) the pushing in of which key by the voter registers the vote, through any suitable mechanism, the mechanism of which need not be herespecified, since my invention may be used indifferently with any counting or registering mechanism actuated by a longitudinal movement of a push rod, and such mechanisms are well known in the art, and form no part of my invention.

The push rod 5 has a bearing in a block 6, secured on the base plate 7 which carries the counting mechanism (indicated in dotted lines at 8), and the inner end of said push rod 5 is secured to a plate 9, which increases in width rearwardly and carries at its rear edge the transverse channel 10. Said channel is formed of two parallel vertical walls 11, said walls having, upon their inner or opposing faces, shoulders 12, upon which rest the extreme edges of two horizontal rollers 13, said shoulders being merely of sufficient height to raise the lower faces of said rollers 13 out of contact with the bot tom of the channel 10., Said rollers are pivotally mounted on stud shafts 1st extending downwardly from a cam plate 15, and the rims of said rollers run against the inner faces of the walls 11. The diameter of said rollers is, however, slightly less than the distance between said walls, so that either of said rollers, when bearing against either of said innerfaces, is out of contact with the other inner face. Thus the cam plate can move easily and without friction transversely of the machine, along the channel 10.

The cam plate 15 has, in its rear portion, two cam slots 16, in which work the heads 17 of pins 18, each pin having a vertical bearing in. a hole 19 in the end of a link 20. Each link is mounted on two grooved wheels 21, the grooves of which engage track rails 22, 23, the lower rail 22 being secured on the top of the base plate 7, and the upper rail being secured on the under side of the base plate 7 next above it. By means of the engagement with these rails of the grooves of. the wheels 21, it is impossible for said wheels and links to move except in a transverse direction.

The cam slots 16 divergefrom each other from the rear to the front. -T-hns when the key t is pushed in, the cam plate, with its slots, having a like rearward movement, will cause the links on each side of it to separate a distance equal to the increased distance between the front end of the slots over that between the rear ends thereof. Every key in this machine has this same apparatus or plate 9, ram plate 15, andone link 20, but the cam plate 15 of each key is connected not only with its own link 20, but with the front or left hand end of the link belonging to-the next succeeding key, (from left to right), every link (except those in the first-cdlumn) having a hole in each of its ends and carrying in each of said holes one of the pins 18. lf now all the keys in the same row are connected through the cam plates 15 and links 20, and if all the links on both sides of their cam plates are equally free to move, then the effect of pushing in one of the keys of the row will be to move all the links on the right of said key slightly to the right, and thelinks on the left of said key slightly tothe left, the distance moved being the transverse shift of either cam slot 16. The extreme right hand end of the line of links is, however, fixed to its plate 7 by a vertical rod 123 passing through all the holes at said extreme end and through holes in the plates 7 at said end, as shown in Fig. l, and the result is that none of the links to the right of any key which is pushed in move at all, but the links to the left receive a double transverse movement, that due to the transverse shift of both the slots in the cam plate actuated.

hen any link is shifted transversely, it"

carries with it its cam plate 15, whose rollers move freely along its channel 10, preventing binding of the cam plate 15 in its transverse movement across its plate 9. It is evident that -'the movement of any link due to the pushing in of its key, or of any key behind it, will be the same, however far the corresponding cam plate 15 may have been previously moved transversely along the channel 9, due to previous operations by the voter' ofkeys in the same horizontal row. And the transverse movement due to the pushing in of each key is transmitted to the front end of the train-of links, and is added to that due tothe pushing in of the other keys at the left hand of each row' as shown in Fig. 1. The first link of the train of links in each row has the .hole 19 to receive one of the pins 18 only in its right hand end, its left end having an axial pivotal connection 30, as shown in detail in Fig. 14, with a tube 31 carrying a crank arm 32 from the outer end of which extends, in a direction parallel to the tube 31, a tube 33. A long pivot pin 34 connects said tube with a similar tube 35 likewise connected by a crank arm 36 with a short tube 37. Said tube 37 forms a-bearing for the end of a bearing against the other end of said tube Thus any movement, in either direction of its reciprocation, of any of the links 20 of a row, will, through the medium of the tubes 31, 33, 35, 37, and swinging cranks 32, 36

impartan equal longitudinal movement to the block 39. At the same time this construction permits the block to have a free vertical movement above or below the plane of movement to which the line of links 20 is restricted, the limit of said Vertical movement being somewhat less an the sum of the lengths of the arms 32, 36. The block 39 has a series of steps 42 spaced at a distance equal to the transverse shift of the links due to the pushing in of one key, and;

stop blocks 39, by reason of said steps, gradually increasing in thickness. The necks 40 of said blocks normally rest between rollers 43 moving in a vertical channel 44, and to limitthe amount of said movement certain of the rollers are fixed in position by means of bolts 145 passed through the rollers, which are hollow and through holes 45 in the opposite vertical walls'of the channel, and there secured by nuts 46. The vertical "channel is thus divided into compartments corresponding to the ofiices to be filled. The centers of the holes 45 in said vertical walls are spaced apart the distance from center to center of keys measured vertically, so that changes can easily be made inthe machine to suitdifi'erent elections.

It is desirablethatthevertical space be tween keys should be as; small as will permitof convenient manipulation of the keys, say,

one half inch from keyto key. If there are sevenparty columns and one column for the scattering votes each ofiice lint will have eight keys therein, and each stop block 39 must have eight steps. If a thickness of the neck of the stop ,block sufiicient for strength be allowed, the height of each step would then be possibly smaller than would be desirable sov as to safely permit a sufli ciently loose fit of the rollers and wedges or stop blocks in the vertical channel 44 when they fill any compartment thereof. The height of each step may be greatly increased without increasing the distance be tween keys by constructing each stop block with a central plate 50, from which rise two stepped side fins51and depends one stepped central fin 52. The central fin ofeach block slides between .the side fins of the block next below it. But when the block is pushed in between the rollers, both-the upper and lower fins tend to spreadthe rollers and the united action is greater than that which would be attained with a single graduated wedge. It

will thus be seen that the links 20 of each horizontal row constitute a of links vertical compartment.

connected by the cam plates 15. By reciprocating a key in said'row, said .train of links is changed in length. In the form of filled. The filling up of the compartment of course prevents the further operation'of any other train corresponding to the said Said vertical compartment, the rollers and the blockstherein thus constitute an interlocking mechanism for all the trains. of-the links and spreaders or cam plates.

If it is intended to employ a machine in which the voter can, change his vote before leaving the booth without erroneously affecting the registering device, the above in terlocking mechanism lends itself readily to this construction: for the effect of retracting the voting key will be to withdraw the links of the train, on the left, as far as they were previously advanced when the key was pushed in. Also all the trains of links and likewise the stop blocks will be returned to their normal position, when all the keys which havebeen actuated are returned to their normal position. The keys are returned by amechanism such as that illustrated in Figs. 2 and 3, in which shafts carry a bar 60 on the top of the machine, operated by the exit of the voter, rocks cranks 61 on vertical rock shafts 62, which rock arms 63, one for each unit of the machine, saidarms engaging bosses (35 on the rods 5 to restore the same, to their normal position. This construction also lends itself to voting a straight ticket vote, which will be done by depressing the lever 70. This lever has connected thereto a crank 71 which Rigidly connected to said shaft are the springs 74, the outer ends of which springs engage with the pins 75-011 the arms 76, which arms are loosely mounted on the shaft 73. When the shaft 73 turns the arms 76 engage with thechannels 10 in its column and moves all thekeys 5 connected thereto to voted position.

The units of the machine are assembled in vertical columns, and are tied together first, by means of rods 80jpass1ng through apertures in the base plates 7, said plates being spaced vertically by sleeves 81 around said rods: Thevplates 9 are slotted, as at said rod 83; thirdly, .by -rods 85 passed through apertures 86 in the front left hand corner 'of the plates. The-adjacent columns are assembled, horizontally, first bymeans' of ears87, projecting from'the sleeves 84 into the next column, and lying betweenapertures 88 in the plates 7- of said column, and rods 89 passed through said apertures 88 and through apertures 90 in the ears, and secondly by the rods 85 which are passed not only through the apertures 86 in the \plates, but also through apertured forked extensions 02 of the blocks 6. Between said extensions 92 are passed the. hinges 86 of the front plates 04: which carry the names of ,the candidates, the rod 85 thus serving as a hinge pin. The other edge of said plate carries hooks 95, which come behind lugs 96 carried by a flat rod 97 passing through holes in the plates 7. By lifting the rod 97 the plate Detjs free to swing on its pivot, and, on dropping said rod, said plate is latched thereby.

The arrangement for voting the scattermg vote comprises a roll of paper 98 covcred by lids 00 which are operated by,the keys to uncover spaces on the roll on which the voter can write the names of un-nominated persons. Said keys are restored to their normal positions in the same way as the other keys. The blocks 39 are inclosed in a vertical channel 100, of thin metahsubstantiall-y U-shaped in horizontal section, enlarged laterally near its open end toform the vertical channel 44 for the rollers, and being strengthened on each side by the U- shaped beams 101, of thick metal, which, with the thin metal lining, form the vertical walls of the channel, both the thick and the thin metal being apertured to permit the bolts 145 to pass therethrough. Said channel is surrounded on three sides by thin horizontal plates l03,-alining with. the base plates 7, said plates 103 being turned up,

as shown at 104, to earrya bearing 105 for' the tube 31, and being also turned upat 106 and secured to the side of the channel 100. Said plates 103 are turned up to form vertical portions 109, each secured to the plate 103 above it, which portions 109 also contain the ends of strengthening rods 110 which enter the tubes 31 and upon which said tubes slide in their reciprocation.

It will be observed that this whole arrangement of interlocking mechanism has for its object to reduce the vertical distance between the keys to the smallest possible dimensions, while still permitting interlocking between keys of ditferent rows and diftwo and one-half to three inches long, which isthe most convenient form of name space, permitting the name to be printed in large bold type easily read by the voter. 'In the voting machines now upon the market the name space is generally an inch square, providing too great a height and too short a length, necessitating the name being broken up, the initials being placed above and the surname below and even then requiring the use of small type to place the name in this short name space. By my invention ample space is provided for the name without unduly increasing the front surface of the voting machine. This construction also enables the names of all candidates of the same party to be placed in the same column. The front of the voting machine therefore in my construction corresponds nearly as possible with that of the ordinary form of ballot sheet in use where voting machines are not employed.

I shape my stop blocks 39 with the successive steps on each side thereof to increase the accuracy and safety of the interlocking mechanism as a whole. It will be seen that if the .bevels connecting the successive steps contact with the spreading rollers 43, a very slight forward movement of the stop block 39 will cause the rollers to spread as much as though the stop block were advanced the full-length of the step. Only a small fraction of the forward movement of each step is active in spreading the rollers. The rest ofthe forward movement in spreading the stopbloek is idle, so that the stop block, having overcome the. resistance of the rollers at the beginning of its movement for each step, will move through the balance of its movement with the greatest of freedom, and .in turn the crowding, together of'the rollers by the movement of another stop block will not react on the stop blocks that.

have already been advanced, tending to return them to their original position. Furthermore, after the stop block has spread the rollers it throws no bending stress whatever on the channel 44 until the next step of the stop block encounters the rollers. If the stop block has been forced to voted position by undue pressure, it no longer tends to spring the channel 44 in the direction of the movement of the stop block but can only exert a longitudinal stress along the chani said spreading one end of the trains,

part of the interlocking the links 20 is pressed in,

nel. It has been found that this result is a material one in interlocking mechanisms of this type, in which the springing of the channel in the direction of movement of the stop blocks can sometimes introduce a serious error into the working of the,interlock.

It will be seenhthat the cam plate 15 is the'equivalent in some respects to the Wedge that has been used in interlockingvmechanisms heretofore, and that the links 20 correspond in some respects to the blocks that have been used in interlocking mechanisms heretofore, and for convenience these parts may be referred to by the terms wedge and block respectively. It will also be seen that the stop block 39 may properly be called a Wedge or a progressively movable Wedge, or interlocking Wedge, for such in effect is its function,

system of the Ina-- chine.

It is obvious-that numerous changes may be made-,in the details of my invention Without departing from the spirit of it. For example, the plate 15 may be reversed so as to make draw together when the key cured by drawing the key out to voted po sition instead of pushing it in. It is also obvious that the stop blocks 39 may be pushed into engagement With the rollers 43 instead of pulled into engagement therewith, and if the position of the cams 16 be changed to make the links draw together the stop blocks 39 can be drawn in directly by their respective trains.
